Worldwide, osteoarthritis (OA) is the most common cause of joint pain in older people. Many factors contribute to osteoarthritis’ development and progression, including secondary osteoarthritis’ underlying causes. It is important to note that osteoarthritis affects all four tissues: cartilage, bone, joint capsule, and articular apparatus. An increasingly prominent area of research in osteoarthritis regulation is microRNAs (miRNAs), a small, single-stranded RNA molecule that controls gene expression in eukaryotes. We aimed to assess and summarize current knowledge about the mechanisms of the action of miRNAs and their clinical significance. Osteoarthritis (OA) is affected by the interaction between miRNAs and inflammatory processes, as well as cartilage metabolism. MiRNAs also influence cartilage cell apoptosis, contributing to the degradation of the cartilage in OA. Studies have shown that miRNAs may have both an inhibitory and promoting effect on osteoporosis progression through their influence on molecular mechanisms. By identifying these regulators, targeted treatments for osteoarthritis may be developed. In addition, microRNA may also serve as a biomarker for osteoarthritis. By using these biomarkers, the disease could be detected faster, and early intervention can be instituted to prevent mobility loss and slow deterioration.
Sambucus nigra L. has been used for centuries in traditional medicine thanks to its valuable healing properties. The healing properties result from its high content of biologically active compounds, mainly antioxidants, which contribute to its anti-inflammatory and anticancer properties. In our review, we have presented scientific studies evaluating the anti-inflammatory and anticancer effects of extracts and their components from S. nigra L. flowers and fruits. The results of the research show that the effect of antioxidant phytochemicals contained in their composition reduces the level of free radicals and pro-inflammatory cytokines, prevents mutations that increase the risk of cancer development, and inhibits cell proliferation, induction of apoptosis, and changes in intracellular signaling, consequently inhibiting the growth of malignant tumors and the formation of metastases. Flowers and fruits of S. nigra L. are a valuable source of nutraceutical and pharmacological substances that can support prevention and anti-inflammatory and oncological therapy without negative side effects for the patient.
Black garlic (BG) is a fermented form of garlic (Allium sativum L.), produced at precisely defined temperatures, humidities, and time periods. Although garlic has been used for thousands of years, black garlic is a relatively new discovery. There are many bioactive compounds in black garlic that give it medicinal properties, including anti-inflammatory and anti-cancer properties. In our review article, we present scientific studies examining the anti-inflammatory and anti-cancer effects of black garlic. According to research, this effect is mainly due to the reduction in the production of pro-inflammatory cytokines, as well as the ability to scavenge free oxygen radicals and induce apoptosis. In addition, the phytochemicals contained in it have antiproliferative and antiangiogenic properties and inhibit the growth of cancer cells. Black garlic is a valuable source of biologically active substances that can support anti-inflammatory and anti-cancer therapy. Compared to Allium sativum, black garlic has fewer side effects and is easier to consume.
Introduction and aimThe rapid spreading of SARS-CoV-2 virus, higher incidence and mortality over population and also insufficient knowledge about the etiology of this disease and methods of its elimination is a problem of modern virology. Series measures are performed to implement an accurate forms of therapies for COVID – 19 patients and convalescents. The purpose of this article is to conduct a review of the latest surveys about effective treatment methods of SARS-CoV-2 infected patients.Brief description of the current state of knowledgeIn order to do this, 46 scientific records from 2019 - 2021 published in the PubMed scientific database were included. The most known, efficient methods of COVID-19 therapy included therapy of tocilizumab, remdesiwir and amantadine, which were used separately.ConclusionIn our review promising therapies and medicaments, which can be used in COVID-19 practice were described. However, none of presented therapies has turned out in 100% efficient in the treatment of COVID-19. The profiled recommendation should be further combined to refine and formulate new effective treatments for SARS-CoV-2.
Background: The purpose of this study is to compare and analyze research studies focused on orthorexia nervosa (ON) as a spectrum of eating disorders, and to summarize potential risk factors in different age and social groups. ON is characterized by an obsession with healthy eating, which leads to a restrictive diet and health problems. Methods: Due to a lack of comprehensive analyses, this review re-examined studies from 2006 to 2023, initially retrieving 53,134 articles. Upon refining the criteria and risk factors for eating disorders, 34 notable records were identified. These studies employed diagnostic tools such as ORTO and BOT, focusing on risk factors for ON. Results: Results indicate that individuals suffering from eating disorders, losing weight, exercising heavily, developing relationship problems, and suffering from body dysmorphic disorder are at high risk of developing ON. A significant correlation was found between ON, BMI, and gender, but not between ON and OCD. Interestingly, ON symptoms appear to overlap with those of other eating disorders, such as anorexia and bulimia, especially in terms of obsessive control over dieting and fear of gaining weight, indicating a close relationship between the two. Conclusions: Interestingly, orthorexia nervosa may serve as a coping mechanism for anorexia, providing a sense of control. However, further research on its long-term effects is required.
The purpose of this study was to evaluate the effectiveness of Neurofeedback therapy in children who have mild symptoms of autism or attention deficit disorder. The method we used is widely regarded as safe, non-invasive, and can be used in conjunction with other therapies for people with autism spectrum disorders. The study we conducted is a pilot study, which will serve as a foundation for more comprehensive research.A study was conducted with six children aged 8-10 years with high-functioning Autism Spectrum Disorder (ASD) and Attention Deficit Disorder (ADD). Neurofeedback was administered to all patients. The subject of the analysis was to assess the change in brain wave range with eyes closed, before and after Neurofeedback therapy.Following Neurofeedback therapy, significant differences were observed in Delta, Beta1, Beta2 and SMR waves. It was found that the amplitude of the Delta wave and Beta1 wave at the Cz point was higher prior to NFT treatment, whereas the amplitude decreased significantly following this intervention. Furthermore, the amplitudes of Beta2 and SMR waves were observed to increase in the parietal area P4.Neurofeedback can be a valuable approach to augment other therapeutic methods used in children with autism, particularly in the context of improving executive functions. Our study demonstrated that Neurofeedback is beneficial for treating individuals with combined disorders: ASD and ADD, adapting therapy to each child's needs. Our research and analysis of the results obtained by other authors confirm that it is necessary to create individual profiles of children with ASD using EEG due to the different specificity and intensity of symptoms and the presence of various disorders accompanied by this dysfunction. It depends largely on differences in the neurophysiology of ASD patients and additional conditions, primarily the degree of brain damage. It is therefore necessary to conduct further research in this area.
Electroencephalography (EEG) is a non-invasive diagnostic tool, enabling us to assess the electrical activity of the brain and its disturbance in a great number of psychiatric conditions. This paper provides a narrative overview of the most recent advantages of EEG use in various psychiatric disorders that are associated. This article analyses selected psychiatric disorders. We discussed anxiety disorders characterized by chronic fear, dementia leading to cognitive decline, schizophrenia disrupting logical thinking, bipolar affective disorder with alternating episodes of mania and depression, and depression manifested by gradual loss of vital energy. We have shown that EEG testing, by monitoring the electrical activity of the brain, is a helpful tool in identifying specific brain wave patterns associated with these disorders. In the study of mental illness the EEG variant called quantitative EEG (QEEG) is of particular avail as to the spatial discrimination. QEEG is based on digital coding and transformation according to Fourier algorithm. Recently, even more complex methods of EEG data analysis have been implemented, including artificial intelligence (AI), deep learning (DL) and its branch: machine learning (ML). The use of sophisticated EEG postprocessing adds important information about the pathophysiology of mental disorders. More so, EEG/QEEG recording (in particular spectral analysis), if repeated over time may help to follow up the treatment results and to establish a prognosis as to the course of the given condition. Reliability, safety and availability of EEG makes it to be an indispensable tool in modern psychiatry. Use of EEG, QEEG may lead to faster and more precise differential diagnostic workup. Use of EEG/QEEG changes as an objective outcome measure in clinical trials may support the development of personalized pharmacotherapy or psychotherapy.
Bioactive molecules present in plant products determine their very valuable health-promoting properties. Among the plants, due to these properties, particular attention is paid to the seeds of common flax (Linum usitatissimum L.), which have been used for over 6000 years and are known for their benefits. A review of 117 scientific articles indexed in PubMed/MEDLINE, ScienceDirect, and Wiley Online Library, published between 1997 and 2024, was conducted. These seeds are characterized by a high content of valuable nutrients, such as essential omega-3 fatty acids, including α-linolenic acid (ALA), lignans, isoflavones, phytoestrogens, flavonoids, vitamins, and minerals that influence the digestive system function and have anti-cancer properties. The presence of these bioactive compounds in flaxseeds provide anti-cancer properties.
Globally, osteoporosis is the most common systemic skeletal disease. There are many factors that influence osteoporosis’ development and progression. During the pathogenesis of this disease, bone turnover is imbalanced between resorption and the formation of bone tissue. A growing interest has been devoted to the role that microRNA (miRNA) plays in osteoporosis regulation. A microRNA (miRNA) is a group of small single-stranded RNA molecules involved in regulating gene expression in eukaryotic organisms. As microRNAs (miRNAs) are key regulators of gene expression and can modulate processes related to bone metabolism, they have become increasingly important for studying osteoporosis pathogenesis. The available research suggests that miRNAs play an important role in regulating processes associated with bone metabolism, especially by influencing bone resorption and synthesis. Furthermore, microRNAs can also serve as potential therapeutic targets for osteoporosis, besides being a rapid and specific biomarker.
